Sounds like an IRQ-related problem - the audio driver works fine,
but doesn't get notified properly when the next chunk of data is
required. If there's a way to tinker with the ac97 IRQ settings
(usually provided in the BIOS setup menu), try something in the
lower (1-15) range - IRQs above 15 require a slightly different
handling method.

Other options... try an ACPI-enabled kernel (or vice versa),
double-check that you've got 82cxx turned on in the kernel settings
(VIA82CXXX option in the ATA/IDE block devices menu), maybe even
turn on the local APIC option as well.

good luck...
